SMMs grammar is near impeccable, whereas the paragraph you posted above has several errors that someone with a 4th grade education in English would not make. SMM did make some spelling mistakes but they were rather infrequent. It is doubtful that he would feign different levels of fluency under his real name vs. his psuedonym on getbig. It just makes no sense.
No they aren't infrequent at all. Not true.
He constantly makes spelling errors, and
it is a fact that SMM is not a native english speaker. I just pulled up a random post about Usher and there's a spelling error. Also, Melao is probably playing up his 'foreignness' for Americans that are succeptable to his bullshit. Foreign = mysterious to Americans.
I don't know why it's so hard to believe that this guy is really not 300 pounds and ripped. Is it that shocking that he's a skinny geek living out a fantasy on this website and cracking himself up until it got real? It's not unbelievable at all. He's even said himself that we are just here to rile up for his amusement whenever he wishes.
